Özet

Additively manufactured IN939 (AM-IN939) is promising for aeroengine turbine blades, where high-temperature oxidation resistance is essential. This study aims to enhance AM-IN939's high-temperature cyclic oxidation performance by applying nickel aluminide (NiAl) coating via the chemical vapor aluminizing process. Cyclic oxidation tests at 1050 °C for 240 cycles show a stable α-Al₂O₃ layer on NiAl-coated specimens, leading to weight gain due to its protective properties. Uncoated specimens form nonprotective oxides, including Cr₂O₃, TiO₂, CoCr₂O₄, and NiCr₂O₄, resulting in weight loss from spallation, with internal oxidation and nitridation observed. Overall, the NiAl coating significantly enhances the high-temperature cyclic oxidation resistance of AM-IN939.
